(void) | - startAnimation [implementation] |
(void) | - stopAnimation [implementation] |
Manages an animation. Contains timing and progress information.
-(BOOL)animationShouldStart:(CPAnimation)animation; Called at the beginning of -startAnimation
.
animation | the animation that will start |
YES
allows the animation to start. NO
stops the animation.-(void)animationDidEnd:(CPAnimation)animation; Called when an animation has completed.
animation | the animation that completed |
-(void)animationDidStop:(CPAnimation)animation; Called when the animation was stopped (before completing).
animation | the animation that was stopped |
- (float)animation:(CPAnimation)animation valueForProgress:(float)progress; The value from this method will be returned when CPAnimation's currentValue
method is called.
animation | the animation to obtain the curve value for | |
progress | the current animation progress |
Definition at line 80 of file CPAnimation.j.
- (CPAnimationCurve) animationCurve | [implementation] |
Returns the animation's pace

- (void) animationTimerDidFire: | (CPTimer) | aTimer | [implementation] |
Definition at line 237 of file CPAnimation.j.
- (float) currentProgress | [implementation] |
Returns the animation's progress
Definition at line 294 of file CPAnimation.j.
- (float) currentValue | [implementation] |
Returns the animation's timing progress.
Definition at line 302 of file CPAnimation.j.
- (id) delegate | [implementation] |
Returns the animation's delegate
Definition at line 200 of file CPAnimation.j.
- (CPTimeInterval) duration | [implementation] |
Returns the length of the animation.
Definition at line 171 of file CPAnimation.j.
- (float) frameRate | [implementation] |
Returns the desired frame rate.
Definition at line 192 of file CPAnimation.j.
- (id) initWithDuration: | (float) | aDuration | ||
animationCurve: | (CPAnimationCurve) | anAnimationCurve | ||
[implementation] |
Initializes the animation with a duration and animation curve.
aDuration | the length of the animation | |
anAnimationCurve | defines the animation's pace |
CPInvalidArgumentException | if an invalid animation curve is specified |
Definition at line 101 of file CPAnimation.j.
- (BOOL) isAnimating | [implementation] |
Returns YES
if the animation is running.
Definition at line 277 of file CPAnimation.j.
- (void) setAnimationCurve: | (CPAnimationCurve) | anAnimationCurve | [implementation] |
Sets the animation's pace.
anAnimationCurve | the animation's pace |
CPInvalidArgumentException | if an invalid animation curve is specified |
Definition at line 122 of file CPAnimation.j.
- (void) setCurrentProgress: | (float) | aProgress | [implementation] |
Sets the animation's progress.
aProgress | the animation's progress |
Definition at line 286 of file CPAnimation.j.
- (void) setDelegate: | (id) | aDelegate | [implementation] |
Sets the animation's delegate.
aDelegate | the new delegate |
Definition at line 209 of file CPAnimation.j.
- (void) setDuration: | (CPTimeInterval) | aDuration | [implementation] |
Sets the animation's length.
aDuration | the new animation length |
CPInvalidArgumentException | if aDuration is negative |
Definition at line 160 of file CPAnimation.j.
- (void) setFrameRate: | (float) | frameRate | [implementation] |
Sets the animation frame rate. This is not a guaranteed frame rate. 0 means to go as fast as possible.
frameRate | the new desired frame rate |
CPInvalidArgumentException | if frameRate is negative |
Definition at line 181 of file CPAnimation.j.
- (void) startAnimation | [implementation] |
Starts the animation. The method calls -animationShouldStart
: on the delegate (if it implements it) to see if the animation should begin.
Definition at line 219 of file CPAnimation.j.
- (void) stopAnimation | [implementation] |
Stops the animation before it has completed.
Definition at line 261 of file CPAnimation.j.
